Noobish question..

I guess you mean "connected" on the console. What about this:
| Code: | #!/bin/bash
for name in $(users)
do
uinf=$(cat /etc/passwd | grep $name)
if [ -z "$uinf" ]
then
echo "User listed in users does not exists in /etc/passwd"
else
usr=$(echo $uinf | cut -f1 -d:)
id=$(echo $uinf | cut -f3 -d:)
echo "User $usr UID $id"
fi
done
